FLOWN APOLLO 11 FLIGHT PLAN SHEET.
Apollo 11 Flight Plan, pp 3-99/3-100, a single sheet printed recto and verso. NASA/MSC, July 1, 1969. 10½ x 8 inches. Extensive annotations by Armstrong in ink and by Collins in pencil. With a Typed Letter Signed by Buzz Aldrin.
Neil Armstrong was preparing the spacecraft to bring his crew home to earth. The day before, he and Buzz Aldrin had completed the first part of President John F. Kennedy's national goal of landing men on the moon. The next step was to begin the procedure to return safely to earth. Armstrong records critical navigation data and verifies that steps to ignite Columbia's large rocket engine have been accomplished.
Accompanied by BUZZ ALDRIN'S letter, which reads in part: ""Enclosed with this letter is a page numbered 3-99 and 3-100 from the Apollo 11 Final Flight Plan... The page is from the detailed timeline section and covers the beginning of the critical Transearth Injection (TEI) burn by Columbia. This spacecraft burn had to work. If it did not, Neil Armstrong, Michael Collins, and myself would remain in lunar orbit, never to return to earth.
During the mission, Michael Collins entered '@137:24' on page 3-99 which was the mission time a carbon dioxide filter was changed, a bit later than scheduled. We were very busy getting ready for the important TEI burn. Neil Armstrong checked-off each step listed on page 3-100 as they were performed or marked out ones no longer needed to be carried out. Neil also recorded our guidance platform realignment program (P52) N(oun) values of '01, 11, 000.01' and the N(oun)93 values of '+00.166, +00.212, -00.019.' He logged these values at a GET of '134:34' (hours and minutes) into the mission. These were the REFSMMAT or Reference Stable Member Matrix residual values based on Eagle's guidance platform during lunar lift-off... I have written on page 3-100: 'Carried to the Moon on Apollo XI' and signed it along the bottom of that page."
